AUTOMATIC FLOOD-GATE.

SPECIFICATION formingpart Of Letters Patent NO. 433,366, dated July 29, 1890. Application filed October 24, 1889- serial No. 327,993. (No model.)

.To all whom it mag concern:

Be it known that I, MADISON QUIsENBEERY, of Raymore, Cass county, Missouri, have invented certain new and useful Improvements in Automatic Flood-Gates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to automatic floodgates; and it consists in the novel construction and parts hereinafter set forth and described.

The object of my invention is to provide a means of closing gaps in a fence where it crosses small streams of water, which, 011 00- casions of heavy falls of rain, suddenly rise, thereby making it impossible to construct an ordinary fence which would stand the freshet across the stream.

My flood-gate is so constructed by means of substantial posts set in the ground, to which the gate is firmly secured by heavy wroughtiron hinges, and posts and weights at either side firmly attached to the gate, as to keep it in an upward closed position, except when the water is very high. In times of freshet the water rushes over the gate and presses it down in a position parallel with the bed of the stream, and as the water recedes the weights located at either end of the gate bring the gate back to the position for which it is designed, closing the in the fence caused by the stream.

Figure 1 is a perspective view of my improved flood-gate, showing the general construction of the same. Fig. 2 is an elevation of the under side of the gate. Fig. 3 showsa detail view of the central horizontal timber and truss-braces. Fig. 4 is a view, partly in section, showing the operation of my improved gate; and Fig. 5 is a detail view of the hinge.

Posts'O and C are set in the ground a few feet up the stream from posts B B,with fenceboards Lreaching from one to the other, closing up the gap between them and posts B. and also forming a chute .for the water and drift-wood to pass over the gate. 7

A is the gate; B, the post to which the weights are suspended; C, an ordinary bracepost.

E are posts set firmly in the bed of the stream-one in the center and one at each side to which the gate is hung.

F is a timber at the lower edge of the gate, forming the hanger, to which the slats of the gate are made fast.

G is a sill spiked fast to the short posts horizontally across the bed of thestream This sill is designed to close up the open space below the gate in seasons of very low water.

I I are the slats of the gate.

J J are strong braces securely attached at each end, the two lower ends extending in ward to the center of the gate, the upper ends extending outward, to each of which a rope is secured, carrying a weight, which weights operate the gates. These braces are made very strong and are firmly secured to the gate, the main object of them being to carry the weight of the gate and prevent it from sagging.

K is another horizontal timber, to which the slats of the gate are made fast.

H are braces, which are rigidly secured to the bot-tom timber F, to the center timber K, and to the braces J The object of these braces is to make-the gate more solid at the ends.

m m are the weight-ropes and pulleys, respectively; D, the extreme end of the bracket to which the pulley is attached; (1, a bolt that holds the pulley in position.

a a are the banks of the stream; *5 t', the hinges of the gate. The gate is braced by means of the truss-rods O O, linked at the center and bearing upon the king-pin N, the free ends of the truss-rods passing through the pieces II, and there secured by means of the nuts P P.

Having thus described my invention, what I claim as new, and desire to protect by Letters Patent of the United States, is-

In a flood gate, the combination, with posts E sunk in the bed of the stream, of the gate A, hinged thereto, said gate consisting of the horizontal timbers Fand K, slats I, and pieces H, and braced by the truss-rods O and kingpin N, as described, the upwardly and outwardly extending braces J, the posts 13, sunk in the banks of the stream and provided with In testimony whereof I affix my signature horizontal brackets D, pulleys m, supported in presence of two, Witnesses. r from said brackets, ropes m, connected to the 7 free ends of the brackets J and passing over MADISON QUISENBERRX 5 the pulleys m, and the weights M, attached Witnesses:

to the ends of the ropes, substantially as and S. CAMPBELL, for the purpose described. ALEX KING.
